Many diskette manufacturers put QA info on cylinder 80, side 0, 
including manufacturing date, which can be very handy sometimes.

But I've got at least two drives in my collection that will "hang up" 
on cylinder 82--the head sticks and will not retract--requiring 
manual intervention.  There are other drives where the position hits 
a stop after cylinder 81.

And the manufacturer doesn't QA the media that far anyway.

I suspect that Superdrives and USB floppies won't go out that far, 
though I haven't tested them.
